    1987 Johnson 200 outboard - what is this/these bypssed system(s) ?

    Many Thanks Fazt, I was told that thermostats have been removed and vro has been bypassed. Previous owner pre-mixed his oil. Will post a couple of pics tomorrow. On test shakedown cruise motor ran good and cool, running for our almost hour long test. The pee stream was good too. For...

    1987 Johnson 200 outboard - what is this/these bypssed system(s) ?

    From the two uploaded pics, can someone help me ID the system(s) that have been bypassed on this 1987 200 hp v6 Johnson? In the pic of the starboard side of the motor there is a circular part (with unconnected nipple) attached to the block (or intake) in the center of the pic, partially obscured...

    1987 Johnson 200 outboard - dicsonnecting vro

    I just purchased this 1987 Johnson 200 hp v6 motor and I have a question about disconnecting the vro. The previous owner said that the vro is already disconnected and that he pre-mixes the fuel. I've watched youtube videos on disconnecting the vro, and what I found when I checked my motor wasn't...

    1981 Evinrude 50 hp - questions on changing thermostat components

    I want to change the thermostat components in my 1981 50 hp E50BELCIC 2-cyl 2-stroke, and I'm wondering if I'll be able to pull the head cover and change the thermostat parts without pulling the head or powerhead. It appears that I can get to all the small water cover / head cover bolts, but...

    '81 Evinrude 50HP - Remove starter to drop lower unit ??

    The 1981 OMC manual for the 50-55-60 hp outboard motors says that part of the procedure for removing the lower unit is to remove the starter. I've removed the starter before for other reasons but I don't see why this would be needed on this 50 hp motor to drop the lower unit. I just want to...

    What was last year of 4-cylinder 44 cu in Merc 50 hp outboard ?

    Hi to all, What was the last year that Mercury produced the 4-cylinder 44 cubic inch 2-stroke 50 hp outboard motor ? And did they ever overlap production of the older 4-cyl 50 hp with a newer design 3-cyl or 2-cyl 50 hp 2-stroke outboard ? Many thanks!

    1981 Evinrude 50 hp - Carb rebuild questions

    I've rebuilt some older Merc carbs from 60s-70s vintage, but now I need to rebuild the carbs on our 1981 Evinrude 50 hp 2-cyl 2-stroke outboard (E50BELCIC). I have new kits with floats and the OMC service manual, but I'm hesitant to start the rebuilds when I read about the "core plugs" in the...

    Carb throttle linkage retainer swap - 1981 Evinrude 50 HP E50BELCIC

    I have new nylon/plastic retainers to replace the old ones in the throttle linkage. The old ones have some slop in them. This is for the throttle linkage only. The choke linkage retainers are fine. What is the correct way to remove the old plastic/nylon retainers and install the new retainers...

    1981 Johnson/Evinrude Control (Shift) Box Handle - Throttle play

    My Throttle Control Box ('81 OMC) shifts fine into and out of forward/neutral/reverse, however, the throttle lever on the control box must be advanced an additional couple inches before the throttle cable begins to move at the engine end. The fast idle lever has the same play. I would like to...

    1981 50 HP Evinrude - Linkage tweaking and "slop"

    This is the first time I've posted in a long time and thanks in advance for any pointers. I just purchased a 1981 Evinrude 50 hp outboard that has been pretty well cared for but needs some tweaking. Spark and compression are ok. So far, I've replaced the fuel pump and fuel lines from engine...

    Install short-to-long shaft extension – ’67 Merc 1100

    I’d sure like a tip from anyone who has installed one of these short-to-long shaft extension units. I need to swap one of these units from one short shaft motor to another (better) motor. When I removed the lu with extension I saw that the diameter of the drive shaft extension joint was too...

    Poly/Cotton Boat Cover - can I treat with water repellent ??

    Is there a water repellent spray that can be applied to a poly/cotton boat cover to help keep water out? I've seen products like 303 Fabric Guard and Kiwi Camp Dry that I believe are recommended for canvas / cotton-canvas covers. Can these same products be used on a poly/cotton cover as well...

    Question for north40

    Hi Bob, I have an '89 Merc 100HP 2+2 with a bad oil reservoir float/magnet. I read in one of your previous posts that you have fabricated a magnet/float combo for the oil reservoir that wouldn't come un-glued ever again. If you have one you would sell reasonably, or if not, if you could please...

    Accelerator pump problem - '89 Merc 100HP 4-cyl

    During our ski trip this weekend I noticed the accelerator pump not working correctly. This is the first time this has occurred. The motor now acts exactly like many of my older cars when the accelerator pump needed replacing on the carb. The symptom on the Merc now is about a 2-second delay in...

    Speedo sleeve - 1989 Merc 100 HP 4-cyl

    I was cleaning out the clogged speedometer inlet on my '89 Merc 100HP 4-cyl last night as I've done several times before, but this time the stainless steel sleeve came out of the motor. It will go back in easy but feels too loose to leave as is. Is there a recommended way to secure this sleeve...

    Air bubble after replacing oil inject lines - '89 100HP

    I just replaced the plastic lines of my oil injection system from tank to oil pump on my 1989 100HP 4-cyl. (I replaced the oil pump to fuel pump piece last year).<br /><br />But after replacing the line from tank to oil pump, I now have an air gap of about 2 inches where the line meets the "T"...

    Question for prop experts - 1989 Merc 100HP

    I have a 1989 Merc 100HP (4 cyl) that cruises great with a 19" pitch (non-cupped) alum prop and it also does well pulling up a skier on two skiis, but it is very marginal pulling up an adult slalom skier (barely will).<br /><br />What difference would I see by using an 18" pitch stainless steel...

    Basic prop question - 1970 Merc 500

    I've been looking for a NOS prop with correct pitch for my Merc 500 on my fishing boat. Recently I found one but this prop is missing the ring that normally is on the rear of the prop hub. According to charts, with this prop I should be able to turn at or near max recommended RPM at WOT, with...

    Question for BoatBuoy about Gator trailer

    Hi BoatBouy,<br /><br />On my 1959 Gator trailer with "mechanized transom cradles", the handle operates correctly to lift the bunks, but there doesn't seem to be any type of lock/catch/latch on the trailer rail to hold the handle in place when the bunks are lifted. Is there supposed to be a...
